PIPE-CLEANER.-

SPEGIFICA'IION forming part of Letters Patent No. 644,948, dated March6, 1900.

Application filed October 25,1899. Serial No. 734,752. (No model.)

To CLZZ whom, it may concern.-

Be it known that I, OTTO SPAHR, of the city of New York, (New Brighton,)borough of Richmond, in the "county of Richmond and State of New York,have invented a new and Improved Pipe-Cleaner, of which the following isa full, clear, and exact description.

One object of my invention is to provide a device for cleaning the mainstem of a pipe and which will also serve to lift or loosen the tobaccoin the bowl when the latter becomes detrimentally packed at the openingbetween the bowl and the stem.

A further object of'the invention is to provide a cleaning device whichwill not interfere with the passage of the smoke from the bowl to themouthpiece of the pipe and which will be entirely concealed within thestern of the pipe.

Another object of the invent-ion is to pro- Vide a cleaning attachmentto pipes which is a fixture to the mouthpiece and is of such shape thatwhile being a conductor for the smoke it will present scrapingorcleaning edges so arranged that by turning the mouthpiece any particlesadhering to the stem will be removed, the device being also of suchlength and shape that it will extend into the bowl without interferingmaterially with the communication between the bowl and the stem,enabling such communication to be kept open and the heel in the bowl tobe loosened at any time without removing the attachment from the stem.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal vertical section through a pipe and theattachment applied to the pipe. Fig. 2 is a transverse section takenpractically on the line 2 2 of Fig. 1.

i Fig. 3 is a perspective view of one form of the cleaner.

The bowl A of the pipe may be of any desired shape, and the said bowl isprovided with a stem 13, which is shown as an integral portion of thebowl, and the stem in its turn is provided with a mouthpiece C,-whichmay be of any approved construction.

The cleaning device D is provided with a body which is polygonal incross-section and consists of a tubular section 10, having prefferably acylindrical exterior contour and a reduced threaded surface 11, whichreduced threaded surface is adapted to be screwed into the mouthpiece 0,although the attachment may be secured to the mouthpiece in any approvedmanner.

The body portion 12 of the attachment is preferably made solid and isprovided with three flat surfaces, producing three scraping edges 13,and the outer end of the body 12 is brought to a point, as illustratedat 15 in Fig.3.

The body portion 12 of the attachment is provided with an aperture oropening 16, that extends through from one side to the other, and thisaperture or opening 16 is in direct communicationwith the bore or open-'ing 17 in the cylindrical portion 10 of the at tachment or that portionwhich is connected with the mouthpiece C.

When the attachment has been properly se cured to the mouthpiece of thepipe and the mouthpiece is placed in position relative to the stem 13 ofthe pipe, the attachment extends through the stem B until the point 15of the attachment has entered the communication between the bowl and thestem and is visible from the former.

It will be observed, particularly by reference to Fig. 2, that when themouthpiece is turned the attachment is turned also, and its scrapingedges are brought in engagement with the inner wall of the stem B, thusremoving any material that may adhere to the said wall. Furthermore, thepoint of the attachment moves with its body, and consequently the pointwhich extends in the bowl of the pipe will pierce the heel in the pipeand will loosen the tobacco to such an extent that the draft will befree, and it is also obvious that the point of the attachment will clearaway any obstruction liable to clog the opening es tablishingcommunication between the bowl of the pipe and the stem. It isfurthermore obvious that the flattened surfaces of the body consequenton forming the scraping edges admit of the smoke passing freely from thebowl to the aperture or opening 16, from.

whence the smoke is readily drawn through the tubular section 10 of theattachment into the mouthpiece C. It is furthermore obvious presents thesame exterior appearance as a pipe of ordinary construction.

It is obvious that the cross-sectional poly onal shape of the cleanerproduces more'than one canal for smoke in the stem of the pipe, all thecanals leading from the bowl to the mouthpiece. It is furthermoreobvious that the device when removed from the stem may be used forcleaning out the bowl of the pipe.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination with the bowl, stem, and mouthpieceof a pipe, of a cleaning attachment consisting of a body formed with atubular cylindrical portion fitted in the end of the stem and having athreaded extension on which the mouthpiece is fitted, three flattenedsurfaces forming a triangular portion whose three side edges engage theinner walls of the stem at equal distances apart whereby to hold theattachment securely in the bowl and to scrape the walls when theattachment is turned, and a reduced inner end extending into the heel ofthe bowl, there being provided a lateral aperture extending through thebody and communicating with the opening in the tubular portion, as andfor the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

OTTO SPAHR.
